Eagle III is not paged out. It is either called in by phone or sometimes requested over the air. Marcus Dude is correct on the frequencies. If you do buy a scanner make sure it is digital and 700Mhz if you want to listen to just about anything else in Brown County. Brown County Sheriff, GBPD, GBFD, all county fire departments...etc..will be switching over to 700Mhz trunked P25. I have a Radio Shack PRO-106 and I am very happy with it. I have used it on the Michigan state wide MPSCS system and it works good. I also like the way it is programmed.
So what is remaining on VHF? County fire paging will remain on 154.370 and become simulcast (all towers transmit at once). This will become transmit ONLY. Fire units will NOT talk back to dispatch on VHF. Just llike today GBFD will not get paged out on VHF. It sounds like EMS paging may switch to 154.370, I am not sure at this time. Some fire departments are keeping vhf private TAC channels or repeaters. I believe some form of EMS channel will remain county wide for paramedic intercepts from outlying agencies.
Some VHF will also remain on a patchable basis. For example, if there is a major event the comm center will be able to connect a talk group on the 700Mhz system to one of the tower sites in the county on VHF.
I encourage you to consider a digital scanner. They are still expensive but it's really what you need if you want to listen to just about anything public safety in Brown County in the next several months.
